While I am burning the midnight oil I would be really grateful if
someone has the R values for
Wickes 50mm General Purpose Slab Insulation and
Wickes 30mm Heavy Density Slab Insulation.
Thanks if possible,
Liz.

LOL! I'd love to hear the answers you'd get if you went into a Wickes and
asked that.

Most brands of insulation have similar R values for similar materials. I
have figures for a few makes. Can you give any further details about it
(i.e. polystyrene, polyisocyanate, mineral wool, whatever) as Wickes don't
have any details on their pretty useless website.
